Maintenance technology and standards have come a long way over the past several decades. They started with *reactive maintenance*, where operators would wait for a component in a system to fail and then perform maintenance, replacing the broken part with a new one.

Before server-side JavaScript, applications were written in one language for server-side software and a completely different language for client-side software. This split complicated application development, because it required having two sets of software developer talents—or even two separate software developers or teams—one for client-side and one for server-side application development. Server-side JavaScript and the node.js runtime environment have solved this problem.

More and more, industrial assets are becoming Internet enabled and being connected to other digital systems. Monitoring [OEE](https://blog.opto22.com/optoblog/a-brief-overview-of-overall-equipment-effectiveness-oee) and [KPIs](https://blog.opto22.com/optoblog/kpis-for-industrial-automation-and-process-control) in real time from a [mobile device](http://groov.com/) is no longer a pie-in-the-sky application. It’s happening right now, through the convergence of OT and IT. One of the technologies that’s enabling the IIoT is secure digital communication. And to establish that secure communication, you need to have an authority you can trust that can validate the indentity of devices on a network and on the Internet. You have to trust that the encrypted connection you're using is actually connected to the device you want to talk to, and not to some rogue node trying to breach your network and steal your information. That’s where Certificate Authorities come into play in the IIoT.

In this post we’re going to tackle some ideas related to why JavaScript is poised to literally take over the Industrial Internet of Things as the software language of choice for IIoT developers. We’ll also discuss why, if you’re an industrial automation engineer starting to think about the IIoT, it might be a good idea to brush up on your JavaScript skills.
